No Alice, the date wasn't part of the title - I only know the date from my diary of when the photo was taken. If I hover the mouse over any pic in my photo folders it shows the date so presumably that is recorded in the computer memory somewhere. I wondered if there was somewhere I could search for all photos taken for example on 12 February 2010 etc.
My brother somehow got the sound drivers restored on videos to a certain extent, its still a bit jerky but not as bad thanks. None of the kind AB suggestions worked. I do love all the advice given though, and am very grateful to those who are far more techy minded than me.
